Frequently Asked Questions

How does the higher/lower hint work?

After each guess, the game tells you if the secret number is higher or lower than your guess, allowing you to systematically narrow down the possibilities.

What is the optimal strategy for guessing?

The best strategy is binary search: always guess the midpoint of your remaining range. This guarantees finding any number in a 1–100 range within 7 guesses.

Can I adjust the difficulty?

Yes. Easy mode uses a 1–50 range, medium uses 1–100, and hard mode uses a wider range with fewer allowed guesses.
